Ipv6 Address Link-Local - Edge-Core ECS2100-10T Reference Manual

ipv6 address link-local

This command configures an IPv6 link-local address for an interface and enables
IPv6 on the interface. Use the no form without any arguments to remove all
manually configured IPv6 addresses from the interface. Use the no form with a
specific address to remove it from the interface.
Syntax
ipv6 address ipv6-address link-local
no ipv6 address [ipv6-address link-local]
ipv6-address - The IPv6 address assigned to the interface.
Default Setting
No IPv6 addresses are defined
Command Mode
Interface Configuration (VLAN)
Command Usage
◆
The specified address must be formatted according to RFC 2373 "IPv6
Addressing Architecture, " using 8 colon-separated 16-bit hexadecimal values.
One double colon may be used in the address to indicate the appropriate
number of zeros required to fill the undefined fields. And the address prefix
must be in the range of FE80~FEBF.
◆
The address specified with this command replaces a link-local address that was
automatically generated for the interface.
◆
You can configure multiple IPv6 global unicast addresses per interface, but only
one link-local address per interface.
◆
If a duplicate address is detected, a warning message is sent to the console.
Example
This example assigns a link-local address of FE80::269:3EF9:FE19:6779 to VLAN 1.
Note that a prefix in the range of FE80~FEBF is required for link-local addresses, and
the first 16-bit group in the host address is padded with a zero in the form 0269.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address FE80::269:3EF9:FE19:6779 link-local
Console(config-if)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled
